Anything on there that I would consider a valid user, i.e. anything with at least one successful non-spammy edit, never even uses a single number in the username. Do we just disallow any new accounts that use a number anywhere in the username? I know that we have in the past had a couple valid users with numbers in their username. According to the activity log, we have four who have been active in the last 30 days, two of whom have usernames ending in multiple numbers. (Antix1994 and Madmonk77)

We can make a note on the account creation page that certain patterns are not allowed, such as ending in numbers at all, or even go so far as to disallow all numbers in usernames for new accounts only. This would not affect any existing accounts in any way. We would just need to accept that this may affect the future registration of valid users. But it would drop our spambot account signups by about 90%.

Opinions?

Also, anyone with good regex knowledge want to look at the TitleBlacklist page and see if you can figure out their syntax? It looks to me like blocking useraccounts does something like:.*(insertpatternhere).* <newaccountonly>

Wow. There was a steady trickle before, but it seems like wiki has basically been under all-out siege since the 18th December Looks like there's been at least 1800 new user accounts created since then alone.

Maybe we could just have a box like for the game account creation that asks "I am an alien from Mars and I seek to destroy all humans" or something. Or a box that asks something really simple, like "what is the name of the game?". Some scripts can beat captcha, I heard, but I doubt bots could reply to simple questions that don't have the answer on the page?
